IMPROVEDPROCESS FOR DISlNFE'CTING NOXIOUS VAPORS.

Specification forming part of Letters Patent No, 46,3 [7, dated February 14, 1565.

To all whom it may concern:

Be it known that I, WILLIAM ADAMSON, of Philadelphia, Pennsylvania, have invented an and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention consists in the use, for disinfooting and deodorizing the fumes arising from burning, boiling, or fermenting animal matter, of the products of combustion of spent tanbark, old leather, or other material containing tannin, as described hereinafter.

In order to enable others to practice my inner of carrying it into effect.

In establishments where the rendering of is conducted, the noxious vapors arising infect the atmosphere to such an extent that such establishments are a nuisance and a detriment to the public health and comfort, especially in the neighborhood of large cities. I have found by practical tests that these noxious fumes may be effectuallydeodorizcd and the nuisance obviated by employing, in connection with the fuel used in the fire-places of such establishments, spent tan, old leather, or any material containing tannin. 1f the fumes from a tallowehandlers kettle, for instance, be directed to the chimney through which the products of| of combustion he so directed toward the fumes from the boiler as to be mixed therewith, the fumes will be so thoroughly deodorized as to become entirely inoffensive. will be produced in rooms from which the noxious vapors cannot be well excluded by simply burning spent tan in the room. I prefer, however, in all cases, when it can be conveniently done, to direct the fumes to a flue or chimney through which the products ot'combustion must pass.

.I claim as myinvention and desire to secure by Letters Patent-- The use, for disinfecting or deodorizing the fumes arising from bunting, boiling, or fermenting animal matter, of the products ofcombastion of spent tan-bark, old leather, or other material containing tannin, as set forth.

In testimony whereofI have signed my name to this specification in the presence of two subscribing witnesses.

WM. ADAMSON.
